ST7LITE49M(2007) Datasheet - STMicroelectronics
STMicroelectronics
Description
The ST7LITE49M is a member of the ST7 microcontroller family. All ST7 devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set.
Features
◾ Memories
– 4 Kbytes single voltage extended Flash
(XFlash) Program memory with
Read-Out Protection
In-circuit programming and in-application
programming (ICP and IAP)
Endurance: 10k write/erase cycles
guaranteed
Data retention: 20 years at 55 °C
– 384 bytes RAM
– 128 bytes data EEPROM with Read-Out
Protection.
300K write/erase cycles guaranteed,
data retention: 20 years at 55 °C.
◾ Clock, reset and supply management
– 3-level low voltage supervisor (LVD) for
main supply and an auxiliary voltage
detector (AVD) for safe power-on/off
– Clock sources: Internal trimmable 8 MHz
RC oscillator, auto-wakeup internal low
power - low frequency oscillator,
crystal/ceramic resonator or external clock
– Five power saving modes: Halt, Active-halt,
Auto-wakeup from Halt, Wait and Slow
◾ I/O Ports
– Up to 24 multifunctional bidirectional I/Os
– 8 high sink outputs
◾ 5 timers
– Configurable watchdog timer
– Dual 8-bit Lite timers with prescaler,
1 real-time base and 1 input capture
– Dual 12-bit Auto-reload timers with 4 PWM
outputs, input capture, output compare,
dead-time generation and enhanced onepulse mode functions
◾ Communication interface:
– I²C multimaster interface
◾ A/D converter: 10 input channels
◾ Interrupt management
– 13 interrupt vectors plus TRAP and RESET
◾ Instruction set
– 8-bit data manipulation
– 63 basic instructions with illegal opcode
detection
– 17 main addressing modes
– 8 x 8 unsigned multiply instructions
